Suitable hydrolyzable groups are, for example, functional derivatives of the carboxy group, such as its unsubstituted or substituted amides, esters.

Thioesters, orthoesters, iminoethers, amidines or anhydrides, a nitrile group, ether groups such as a methoxy, ethoxy, tert-butoxy or benzyloxy group or lactones and thermolytically cleavable groups, for example esters with tertiary alcohols, e.g. as cleavable groups, for example, aralkyl groups, e.g. a benzyl group.

The hydrolysis is conveniently carried out either in the presence of an acid such as hydrochloric acid, sulfuric acid, phosphoric acid or trichloroacetic acid or in the presence of a base such as sodium hydroxide or potassium hydroxide in a suitable solvent such as water, water / methanol, ethanol, water / ethanol, water / isopropanol or water / diol. -10 to 120 ° C, e.g. at temperatures between room temperature and the reaction temperature of the reaction mixture.

For example, if a compound of formula IV contains a nitrile or aminocarbonyl group, these groups can be converted to a carboxy group primarily with 100% phosphoric acid at 100 to 180 ° C, preferably at 120 to 160 ° C, or also with nitrite, e.g. sodium nitrile in the presence of an acid such as sulfuric acid, wherein it is suitably used simultaneously as a solvent, at a temperature in the range 0-50 ° C.

For example, if a compound of formula IV contains an acid amide group such as diethylaminocarbonyl or piperidinocarbonyl group, this group may be converted to a carboxy group primarily hydrolytically in the presence of an acid such as hydrochloric acid, sulfuric acid, phosphoric acid or trichloroacetic acid in an aqueous solvent such as sodium hydroxide or potassium hydroxide in methanol, ethanol, water / ethanol, water / isopropanol or water / dioxane at temperatures »• · 8 95372 between -10 and 120 ° C, e.g. at temperatures between room temperature and the boiling point of the reaction mixture.

The reaction is carried out preferably in a suitable solvent such as diethyl ether, tetrahydrofuran, dioxane or dimethylformamide at temperatures between -30 and 100 ° C, preferably at temperatures between -20 and 25 ° C.

However, the reaction with the triphenylphosphonium halide of the formula VI is particularly preferably carried out in the presence of a base such as potassium tert-butylate or sodium hydride.

If, in the reaction of a magnesium halide of formula VI, the hydroxyl group of the carbinol primarily formed in the reaction mixture is not cleaved during the reaction, it is cleaved in the presence of an acid such as hydrochloric acid, sulfuric acid, phosphoric acid or trichloroacetic acid in an ethanol such as sodium hydroxide or potassium hydroxide at dioxane temperatures

between 0 and 120 ° C, e.g. at temperatures between room temperature and the boiling point of the reaction mixture.

If, according to the invention, a compound of formula I in which R 2 represents a hydrogen atom is obtained, this can be converted by alkylation to the corresponding compound of formula I in which R 2 represents an alkyl group or a compound of formula I in which R e represents a hydroxyl group 95372 or contains a hydroxyl group, by esterification or amide conversion to the corresponding compound of formula I, wherein R «represents an alkoxy, amino, alkylamino or dialkylamino group.

The subsequent alkylation is carried out primarily in a solvent such as methylene chloride, tetrahydrofuran, dimethylformamide or dimethyl sulfoxide between an alkylating agent such as methyl iodide, dimethyl sulfate, ethyl bromide in the presence of C 20 and 50 ° C.

The subsequent esterification or amide formation is conveniently carried out in a solvent, e.g. an excess of an alcohol such as methanol, ethanol or isopropanol added to the reaction mixture or an amine such as ammonia, methylamine, n-propylamine or dimethylamine 0 and 180 ° C, however, preferably at the boiling point of the reaction mixture.

The resulting compounds of formula I can be further separated into their enantiomers. Thus, the compounds of formula Σ containing only one optically active center can be separated into their optical antipodes by methods known per se (see Ali Linger NL and Eliel WL in "Topics in Stereochemistry", Vol. 6, Wiley Interscience, 1971), e.g. by recrystallization. from an optically active solvent or by reacting with a racemic compound a salt-forming optically active substance, in particular a base, and separating the salt mixture thus obtained, e.g. on the basis of different solubilities, into diastereomeric salts, ΐ2 95372 ψ from which free antipodes can be liberated. Particularly useful optically active bases are, for example, the D- and L-forms of α-phenylethylamine or cinchonidine.

The resulting compounds of formula 1 having at least 2 asymmetric carbon atoms can be separated into their diastereomers on the basis of their physicochemical differences by methods known per se, e.g. by chromatography and / or fractional crystallization. The enantiomeric pair thus obtained can then be separated into its optical antipodes as described above. For example, if a compound of formula I contains two optically active carbon atoms, the corresponding (R R ', S S') and (RS ', S R') forms are obtained.

In addition, the compounds of formula I thus obtained, in which R 1 and R 5 together represent a carbon-carbon bond, can be converted into their cis and trans isomers by conventional methods, for example by chromatography on a support such as silica gel or by crystallization.

The novel compounds of the formula I thus obtained, if they contain a carboxyl group, can then, if desired, be converted into their addition salts with inorganic and organic bases, in particular into their physiologically tolerable addition salts for pharmaceutical use. Examples of suitable bases are sodium hydroxide, potassium hydroxide, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

The compounds of the formulas II to VII used as starting materials are obtained by methods known from the literature or are known from the literature.

The starting compound of formula II is obtained from 13 95372 of the corresponding N-acylamino compound by acylation according to Friedel-Craft, followed by removal of the acyl group, and optionally by subsequent reduction, hydrolysis and / or esterification or by reacting the corresponding magnesium or lithium compound with the correspondingly substituted pyridine compound. such as with 3-cyanopyridine, pyridine-3-aldehyde or pyridine-3-carboxylic acid derivative and optionally thereafter by oxidation.

The compounds of formulas IV, V and VI used as starting materials are obtained by reacting the corresponding amino compound with the corresponding sulfonyl halide.

The compounds of formula VII used as starting materials are obtained by reacting the corresponding halocarboxylic acid with triphenylphosphine or trialkylphosphonoester.

As already mentioned at the outset, the new compounds and their physiologically tolerable addition salts with inorganic and organic bases have valuable pharmacological properties, in particular anticoagulant effects and antiplatelet activity. In addition, they are thromboxane antagonists and inhibitors of thromboxane synthesis, it being particularly noteworthy that the compounds of the formula I have this effect simultaneously. In addition, they also affect PGE2 formation in the lung and PGD2, PGE2, and PGFαα formation in human platelets.

For example, the new compounds A = 6- (2- (4-toluenesulfonylamino) indan-5-yl) -6- (3-pyridyl) hex-5-enoic acid are studied, t 95372 B = 6- (4- (2- (4 (chlorobenzenesulfonylamino) ethyl) phenyl) -6- (3-pyridyl) hex-5-enoic acid, C = 6- (2- (4-chlorobenzenesulfonamino) indan-5-yl) -6- (3-pyridyl) hexanoic acid, D-6- (4- (2- (4-chlorobenzenesulfonylamino) ethyl) phenyl) -6- (3-pyridyl) hexanoic acid and E-6- (4- (2- (4-trifluoromethylbenzenesulfonylamino) ethyl) phenyl) - 6- (3-pyridyl) hex-5-enoic acid in terms of its biological properties as follows: 1. Anticoagulant effect%

Description of methods

Platelet aggregation is measured by the method of von Born and Cross (J. Physiol. 170, 397 (1964)) in the platelet-rich plasma of healthy subjects.

To prevent clotting, 3.14% sodium citrate is added to the blood in a volume ratio of 1:10.

Collagen-induced accumulation.

• · «

The course of the decrease in the optical density of the flake suspension is measured photometrically and plotted after the addition of the agitation trigger. The rate of accumulation can be determined from the slope of the density curve. The point on the curve with the highest light transmittance is used to calculate the "optical density".

The amount of collagen is chosen to be as low as possible, but still to result in an irreversibly flowing reaction curve. Used under the trade name Hormonchemiezn Munchen, commercial collagen. Prior to the addition of collagen, the plasma is incubated at 37 ° C for 10 minutes each time with the substance.

From the measurement results obtained, the EC50 is determined graphically, which means a 50% change in "optical density" in the sense of anti-clumping.

The results obtained from Table I below: 2. Thromboxam antagonistic effect

Human venous blood is treated with 13 mM Na3 citrate to prevent clotting and centrifuged at 170 x g for 10 minutes. The supernatant-rich aqueous plasma above is poured onto a Sepharose-2B column to remove plasma proteins. Samples of the same size of the resulting flake suspension are incubated for 60 minutes at room temperature with the test substance, ligand (3H-labeled) and tracer (14C-labeled) and then centrifuged for 20 seconds at 10,000 x g. The supernatant is removed and the granule is dissolved in NaOH. The 3 H activity above corresponds to the free ligand, 14 C gives the tracer concentration. 3H in the granule corresponds to bound ligand, 14C is used to repair the ligand in the extracellular space. The binding values of the test substance for different concentrations are obtained by iterating the displacement curve and determining the IC50.

The results are obtained from Table I below: 3. Determination of the inhibitory effect of thromboxane synthetase

Human venous blood is treated with 13 mM Na3 citrate to prevent clotting and centrifuged for 10 minutes at 170 x g. The flake-rich blood plasma above is poured onto a Sepharose-2B column to remove plasma proteins. Samples of the same size of the resulting flake suspension are incubated for 10 minutes at room temperature with the test substance or 16 95372 solvent for comparison and incubation is continued for a further 10 minutes after the addition of 14C-labeled arachidonic acid. After stopping with 50 of citric acid, the mixture is extracted with 3 x 500 of ethyl acetate and the combined extracts are blown dry with nitrogen. The residue is taken up in ethyl acetate, placed on an OK film and separated with chloroform-methanol: glacial acetic acid: water (90: 8: 1: 0.8, v / v / v / v). The dried OK films are placed on X-ray film for 3 days, autoradiograms are developed, and active zones are marked on the film. After excision, the activity in the scintillation counter is determined and the inhibition of TXB2 formation is calculated. IC «j0 is determined by linear interpolation.

Pathol, u. Pharmakol. 195. 71-74 / 1940)) by plethysmography. The selected dose of U-46619 (2.5-25 pg / kg i.v.) reduces respiratory volume by 60% or more. 10 minutes before the thromboxane mimetic, repeatedly increasing doses of test substances are administered by intravenous injection. The percentage inhibition of respiratory depression is measured by comparing the effect of U-46619 before and after different doses of test substances. The following table contains the observed EDgQ values determined graphically:

Substance ED50 [pg / kg] A 30 B 29 95372 5. Inhibition of the lethal effect of endotoxin

Male Sprague-Dawley rats are first pretreated one week before the main experiment with intravenous injections of endotoxin (lipopolysaccharide from E. coli 0111: B4) at 0.1 mg / kg. In the main study, a potentially lethal dose of E. coli (40 mg / kg) was injected intravenously and subsequent mortality was recorded over a seven-day observation period.

Experimental animals receive test substance B one hour before the second endotoxin injection and 4, 8, 24 and 48 hours thereafter as an oral suspension in 0.5% tylose. The following table contains the observed values:

Under pressure limitation, guinea pigs anesthetized with ethyl urethane receiving artificial respiration receive an intravenous injection of arachidonic acid (a precursor of thromboxane) and the bronchospasm that occurs is recorded by a modification of the Konzett and Rossier method. Doses of arachidonic acid (0.5 to 2.0 mg / kg) are selected to reduce respiratory volume by approximately 60%. Increasing doses of test substance B are given as an injection 10 minutes before arachidonic acid. The percentage inhibition of respiratory volume reduction is expressed by comparing the maximum reduction after arachidonic acid administration with the corresponding value after pretreatment with the test substance. The ED 50 value for substance B, which was found graphically, is 8.1 μg / kg.

7. Antigen-induced hypersensitivity reaction

Male guinea pigs are sensitized intraperitoneally with 40 mg / kg Oval burniin a adsorbed on aluminum hydroxide, which acts as an enhancer. Approximately 6 weeks later, the same animals are given 0.1 mg / kg mepyramine hydrochloride by subcutaneous injection to reduce the histamine component of the hypersensitivity reaction, which is otherwise very pronounced in guinea pigs. Thirty minutes later, the animals are exposed for 90 seconds to a sprayed 3% solution of ovalburnin in 0.9% saline. Ten minutes after the start of the breath, the animals are killed by a blow to the neck and the lungs * are quickly dissected. The volume of the sweat, the so-called "stress-trigger volume" is measured. The effect of hypersensitivity or bronchoconstriction is associated with an increase in "stress-trigger volume" (see Orazen, I.M. and Austen, K.F., J. Appl. Physiol. 39. 916-919 (1975)).

8. Effect on thromboxane and PGEai formation in isolated lung.

The guinea pigs are killed by a blow to the neck, the lungs are quickly excised and washed with Tyrode's solution through the pulmonary artery.

With the same solution, the lungs are perfused (0.5 ml / min.) And given artificial respiration with negative pressure (frequency: 52 breaths / min., Maximum pressure: -20 cm H2O). Two 0.1 ml doses of bradykinin (0.2 μΜ) are added to the rinse solution for continuous rinsing with test substance B at 1 pM. The control lungs are peephunted without substance. The rinsed solution is collected 2 minutes before and 10 minutes after administration of bradykinin. The aliquots are allowed to stand at room temperature for 20 minutes (conversion of thromboxane A 2 to 32) and then frozen at -20 ° C.

The concentrations of thromboxane B2 and PGE2 are determined by a radioimmunoassay method. The following results demonstrate that 1 μΜ of substance B in lung lavage solution inhibits thromboxane formation, whereas PGE2 formation is promoted:
